Medium Processing Device Inventory Tracking via Temporary Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medium processing devices, errors during collection or replenishment processing make it unclear whether the medium is managed inside or outside the device, leading to uncertainty in inventory management.
Innovation Solution
A device with internal and external storage units, along with a temporary storage unit, uses a conveyor system and a controller to manage the medium, allowing detection and tracking of storage changes during processing, thereby determining the medium's location and updating state information.

Engineering Contradiction Analysis
1Productivity
If collection processing or replenishment processing is performed using internal and external storage units, then the medium can be transferred between storage locations, but it becomes unclear whether the medium is managed inside or outside the device during processing
Solution Approach 1:
The system implements feedback by continuously monitoring the position of media in the temporary storage unit and updating the state information accordingly. When media is detected in the temporary storage unit during collection or replenishment processing, the state information is updated to reflect that the media management location is in transition, providing real-time feedback to resolve the uncertainty about media location
Solution Approach 2:
The temporary storage unit serves as an intermediary between the internal storage unit and the external storage unit. By introducing this intermediate state, the system can track media that is in transition and update state information appropriately, preventing loss of information about media management location
2Measurement precision
If a temporary storage unit is introduced to track medium during processing, then medium location can be determined, but the device complexity increases
Solution Approach 1:
The temporary storage unit is designed to serve multiple functions: it temporarily holds media during transfer operations, enables detection of media position, and provides a reference point for updating state information. This multi-functionality justifies the added complexity by providing comprehensive media tracking capabilities across different processing scenarios

AI summary
A device for processing a medium includes: a conveyor for conveying the medium; an internal storage for storing the medium, the internal storage being disposed inside a body of the device and connected to the conveyor; an external storage for storing the medium, the external storage being disposed outside the body and connected to the conveyor; a temporary storage for storing the medium temporarily, the temporary storage being connected to the conveyor; and a controller for controlling the conveyer to perform at least one of collection processing and replenishment processing, the collection processing being processing of conveying the medium from the internal storage to the external storage via the temporary storage, the replenishment processing being processing of conveying the medium from the external storage to the internal storage via the temporary storage.
